Applicationefiled March 21, 1916. Serial No. 85,682;

To all whom it mag concern:

Be it known that I, CHARLES A. LARsoN, a citizen of the United States,residing at Lemont, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Chimney-Flue Covers, of

which the following is a specification.

In the present method of covering the flue opening in a wall, use ismade of a metal shield or the like which at times becomes red hot,especially when the soot that lodges about the opening starts to burn.These conditions are very bad as they often ignite the wall paper, withcostly and dangerous results of fire to the building.

It is therefore the primary object of this invention to remedy theseconditions by providing a flue cover wherein use is made of refractorymaterial secured to that face of the shield presented to the flue.

Another important object of the invention resides in the provision ofmeans which serves in the two-fold capacity of holding the refractorymaterial secured to the shield and retaining the cover as a unit inproper position upon the wall with respect to the line opening.

The nature and advantages of the invention will be better understoodwhen the following description is read in connection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as fall within the scope of what isclaimed.

In the drawing forming part of this specification like numerals ofreference indicate similar parts in the several views and wherein Figure1 is a perspective view of the device forming the subject matter of myinvention.

Fig. 2 is a transverse sectional view therethrough.

Before entering into a detail description of what is herein shown anddescribed I desire to have it understood that the same is merelyillustrative of one embodiment of the invention to which I do not limitmyself, andthat such changes may be resorted to when desired as fallwithin the scope of what is claimed.

Referring more particularly to the drawing, 10 indicates the shield orcover proper which may be constructed from any suitable material and ofany desired formation. As shown in this instance the shield comprises ametal disk which has secured to the inner face thereof refractory ornon-conducting heatv material 11. The material 11' is positioned withinthe flue opening and protects the shield 10 from being heated to such adegree as to cause scorching or burning of the wall paper, with aliability of firing the building, which is oftentimes the result whenthe ordinary metal shield is subjected to a maximum degree of heatintensity.

While the material 11 may be secured to the shield in any suitablemanner, the invention provides a construction of means functionating inthe two-fold capacity of both securing the material 11 to the shield, aswell as serving to hold the cover in its entirety properly positionedupon the wall. In this connection use is made of one or more strips 12each having a substantially U-shaped intermediate portion with the Uportion of one strip being disposed at right angles to the other asshown in Fig. 2. The parallel portions 13 of each strip are offset as at14;, the offset portions being riveted or otherwise suitably secured tothe inner face of the shield 10, while the entire U-shaped portion ofthe strips including the off-set portions 1% are embedded in therefractory material 11 effectively securing the latter to the shield.The offset portions 14 of the strips are bent at right anglesterminating in the resilient fingers 15, the latter embracing therefractory material 11 and projecting a considerable distancetherebeyond to engage the wall of the flue opening in which the material11 is adapted to be fitted, and through the resilient action of thefingers 15 the cover in its entirety is held in position as will beunderstood. The refractory material 11 is preferably of a lesserdiameter than the diameter of the shield, so that when the material ispositioned within the opening, the shield will engage the wallsurrounding the same.

What is claimed is A cover for flue openings comprising a plug ofrefractory material, a metallic disk arranged at one side of said plug,and having a greater diameter than that of the latter to project beyondthe peripheral edge of the plug, a reinforcing element including asubstantially U-shaped intermediate portion embedded in the plug, theparallel limbs of said element being bent at right angles and restingupon the outer side of the plug flush with the surface thereof, saidright angularly disposed portions being disposed in contactingengagement with the disk and -is secured, and adapted for holding thecover 1 providing means whereby the disk can be operatively positionedwith respect to the riveted or otherwise effectively secured to flueopening.
